    The EX4400 line consists of eight SKUs:

    -The EX4400-48MP, which offers 12 x 100M/1/2.5/5/10GbE and 36 x 100M/1/2.5GbE PoE access ports, delivering up to 90 W per PoE port with an overall total 2200 W of PoE power budget (using two power supplies)
    -The EX4400-24MP, which offers 24 x 100M/1/2.5/5/10GbE PoE access ports, delivering up to 90 W per port with an overall total 1776 W of PoE power budget (using two power supplies). A total PoE budget of 2160 W can be achieved with two optional 1600 W power supplies.
    -The EX4400-24T, which offers 24 x 1GbE non-PoE access ports 
    -The EX4400-24P, which offers 24 x 1GbE PoE access ports, delivering up to 90 W per port with an overall total 1806 W of PoE power budget (using two power supplies). A total PoE budget of 2160 W can be achieved with two optional 1600 W power supplies.
    -The EX4400-48T, which offers 48 x 1GbE non PoE-access ports
    -The EX4400-48P, which offers 48 x 1GbE PoE access ports, delivering up to 90 W per port with an overall total 2200 W of PoE power budget (using two power supplies)
    -The EX4400-24X, which offers 24 x 10GbE SFP+ fiber access/distribution ports
    -The EX4400-48F, which offers 12 x 10GbE SFP+ and 36 x 1GbE SFP fiber access ports

    Each EX4400 model offers a choice of optional 4 x 1/10GbE SFP+,  a 4 x 10/25GbE SFP28 and a 1 x 100GbE QSFP28 extension module. The EX4400 switches include two dedicated 100GbE ports to support virtual chassis connections, which can be reconfigured to be used as Ethernet ports for uplink connectivity. The 100GbE ports can also accept 40GbE optics for virtual chassis connection or uplink connectivity. EX4400 switches also include high availability (HA) features such as redundant, hot-swappable power supplies and field-replaceable fans to ensure maximum uptime. In addition, PoE-enabled EX4400 switch models offer standards-based 802.3af/at/bt (PoE/PoE+/PoE++) for delivering up to 90 watts on any access port. The EX4400 switches can be configured to deliver fast PoE capability, which enables the switches to deliver PoE power to connected PoE devices within a few seconds of power being applied to the switches. In addition, the EX4400 switches support perpetual PoE, which provides uninterrupted power to connected PoE powered devices (PDs) even when the switch is rebooting.
